Evaluating
Internet Sources
The volume of information on the Internet is enormous, with few controls governing the
accuracy or reliability of the information. Simply because information exists on the Internet
or World Wide Web does not mean it is accurate or reliable. It is important, therefore,
that some analysis of Internet information is undertaken before using the information as
a research source.
Authority
- Who is the author and/or sponsoring organization of the site?
- What is the author's or organization's expertise?
- Is the sponsor or location of the site appropriate to to the materials as shown
in the URL or "address"?
Examples:
- .com for commercial sites or for-profit organizations
- .edu for educational organizations
- .gov for governmental bodies or agencies
- .mil for U.S. Department of Defense
- .net for networks
- .org for non-profit organizations
Does the author and/or sponsoring organization provide a "Mail to" link that allows for
feedback or submission of questions?
